BQ40Z50EVM-561: LED display issue

Part Number: BQ40Z50EVM-561

Hi team,

Here's an issue from the customer may need your help:

The LED lights display different states in charge mode depending on the amount of charge.

Requirements: The charge light at the end of the charge is solid, the fast-reaching light is blinking, and the unreached light is off.

However, when charging, all lights that reach their charge will blink once because the LED HOLD TIME 5S is set. The customer would like to know how to the lights that reach their charge to stay on while charging? 

Could you help check this case? Thanks.

Best Regards,

Cherry

    Hello Cherry,

    They can use the LEDCHG bit to enable the LEDs to display while the gauge is in charge mode. I'm not sure if this answers your question, can you clarify further if it does not?

    The customer should be able to find all the information they need in the TRM regarding the LED functionality.

    Sincerely,

    Wyatt Keller
